Thermal Packaging Solutions - Insulation Experts First

TPS Insulated Envelopes - Manufactured Using True Aluminium, Highly Reflective Foil for Maximum Insulation Performance.

Our insulated envelopes are ideal for shipping perishable products like food, drinks, pharmaceuticals and electronic components. They esure that your goods maintain an ambient temperature in storage and during transportation.

ThermaPack envelopes are manufactured in Sheffield, UK using true aluminium foil, unlike most imported foil envelopes which are made from polymer foil and provide less effective thermal protection. The system reflects up to 97% of heat transferred via radiation (sun, heat). ThermaPack Ultra Double envelopes provides the equivalent of 55mm of Polystyrene and ThermaPack Single is similar to 25mm of Polystyrene.

Insulation material options

In addition to thermal protection, they offer moisture protection and physical protection as the envelopes are puncture resistant. They are quick & easy to use, featuring a self-seal tape lip for quick closure.

They are available in two options of insulation material; ThermaPack Single and ThermaPack Ultra Double, with our ThermaPack Ultra Double providing a highly effective radiant barrier at a very competitive price. See the performance comparison chart below for further information about the differences between the options. As a manufacturer we guarantee you will not purchase our product for less.
